Write shout(s): make every letter in s a capital and add ! at the end. Anything that is not a letter stays.

Examples

shout("hi")→'HI!'

shout("")→'!'

The functionstring shout(string s)

main.cpp

#include <string>
#include <cctype>
using namespace std;

string shout(string s) {
    for (char &ch : s) {
        // your code here: make ch a capital
    }
    return s + "!";
}
